AN ACR ACFT FINDS THAT IT IS OVERTAKING ANOTHER ON APCH TO RWY 26L AT ATL. AFTER IT SLOWS TO PROVIDE SOME SPACING; APCH CTL TAKES THEM OFF THE APCH; INSINUATING THAT IT WAS THEIR FAULT FOR SLOWING AND THAT OVERTAKING TFC WAS A FACTOR.

Narrative

WE WERE 'CLRED FOR THE VISUAL RWY 26L; ATL; MAINTAIN 160 KTS TO THE MARKER.' AS WE CONTINUED THE APCH; WE COULD SEE THE TFC AHEAD OF US HAD REDUCED TO 3 MI SEPARATION AND DISTANCE WAS CLOSING RAPIDLY. UNABLE TO CONTACT ATC DUE TO FREQ CONGESTION; I BEGAN SLOWING THE ACFT TO APCH SPD OF APPROX 140 KTS. ABOUT 30 SECONDS LATER; ATC ASKED OUR SPD; THEN IMMEDIATELY ASSIGNED US A HDG OF 360 DEGS AND A CLB TO 4000 FT DUE TO AN ACFT OVERTAKING US. AS WE CLBED OFF THE APCH COURSE IT BECAME OBVIOUS THAT THE CTLR HAD NOT GIVEN ENOUGH SPACING BTWN THE ACFT AHEAD OF US AND WAS TRYING TO INFER OUR REDUCTION IN SPD WAS SOMEHOW TO BLAME. ON THE FOLLOWING APCH WE WERE ONCE AGAIN CLRED FOR THE VISUAL RWY 26L. THIS TIME; HOWEVER; AFTER OUR PREVIOUS EXPERIENCE WITH THIS PARTICULAR CTLR; WE REQUESTED THE FULL ILS RWY 26L AND WERE CLRED FOR THE ILS RWY 26L APCH. ON THIS APCH; JUST AS WE STARTED OUR TURN TO INTERCEPT THE LOC; WE RECEIVED AN RA TO DSND APPROX 1400 FPM. WE HAD VISUAL CONTACT ON WHAT WE THOUGHT WAS THE TFC (HE WAS ON APCH TO THE PARALLEL RWY) BUT JUST IN CASE; I FOLLOWED THE TCASII COMMANDS AND WE NOTIFIED ATC OF THE RA. THE REST OF THE FLT CONTINUED UNEVENTFUL. I REALIZE ATL IS A BUSY ARPT; BUT I FEEL THIS CTLR IS SACRIFICING SAFETY IN AN EFFORT TO HANDLE PEAK TFC. I ALSO FEEL FREQ CONGESTION AT ATL IS A PROB. SUPPLEMENTAL INFO FROM ACN 430341: WE HAD A TCASII DISPLAY THAT LOOKED DIFFERENT OUT THE FRONT WINDSCREEN. WE HAD 2 TARGETS AT 3 NM AND CLOSING -- BOTH ON THE APCH. WE HAD TFC FOLLOWING US ON THE APCH BUT TCASII SHOWED IT NOT TO BE A FACTOR. HOWEVER; THE CTLR SAID THERE WAS INADEQUATE SPACING -- WE SHOULD HAVE MAINTAINED 160 KTS AND BROKE US OUT OF THE PATTERN; HDG 360 DEGS AT 4000 FT. IT APPEARED TO US THAT WE GOT SQUEEZED OUT OF THE PATTERN SINCE WE WERE NOT GOING TO OVERRUN THE TFC AT OUR 12 O'CLOCK POS AND 2 1/2 NM. I DON'T BELIEVE HE ANTICIPATED THE TFC IN FRONT OF US TO SLOW SO ABRUPTLY -- AND IT WAS CONVENIENT TO BREAK US OUT. ON THE NEXT APCH WERE CLRED FOR THE VISUAL -- WE REFUSED AND ASKED FOR THE ILS. ON THE INTERCEPT HDG TO THE LOC (JUST STARTING TO JOIN) WE HAD TFC JOINING 'A' FINAL FROM THE L SIDE. WE TALKED ABOUT OUR OPTIONS JUST BEFORE TCASII TA AND RA. WE DEVIATED R OF THE FINAL AND DSNDED APPROX 400 FT; RPTED IT TO THE CTLR; WHO RESPONDED THAT THE ACFT WAS ON THE APCH TO THE S COMPLEX.
